STAMPING-PRESS FOR ROOFING RIDGE-TILES.

SPECIFICATION forming part of Letters Patent No. 584,374, dated. June 15, 1897. Application tiled May l, 1896. Serial No. 589,823. (No model.) Patented in Germany August 26, 1894, No. 79,988.

To all whom t may concern.-

Be it known that I, FRANZ KUNZEMANN, of Eilenburg, in the Kingdom of Prussia, Germany, have invented a new and Improved Stamping-Press for Roofing Ridge-Tiles with Ridge-Cutting Arrangement, (for which I have obtained a patent in Germany, No. 79,988, dated August 26, 1894,) of which the following is a specication.

This invention relates to a stamping-press for molding flanged roofing-tiles; and the object of the invention is to so form the upper interlocking flanges of the tiles that they will be of an exact even height and perfectin construction.

In the accompanying drawings, Figure l is a side elevation of the press; Fig. 2, a plan of the folding frames 8 and 9, showing them open. Figs. 3 to 7 are vertical sections through the mold, showing the consecutive positions of the parts.

As shown in Fig. l, the press is composed of a table l, to the open top of which the mold 2 is secured. The horizontal section of this mold corresponds to that of the tile to be formed. An ejector composed of a plunger1 3, carrying a number of bolts 4, projects into the mold from below. This ejector has for its object to raise the finished tile out of the mold, and to this effect the bolts etbear against a false movable bottom 2', the upper side of which corresponds in shape to the bottom of the tile.

Reciprocating motion may be imparted to the plunger 3 by a treadle 6 and connectingrod 5.

To the mold 2 there are secured by hinge 7 two frames or lids 8 and 9. The frame 9 may be folded upon frame 8 and both may then be lowered upon the upper edge of mold 2, but both frames may also be swung vertically out of alinement with the mold, (toward the left in Fig. 1.)

The upper side of frame S carries a slide l0, Fig. 2,which is guided by rails 8 of the frame and also by slots 10', that embrace the fixed screws 11. This slide 10 can be moved in the direction of the arrow, Fig. 2, so as to project over an L-shaped slot 12 of the frame,which corresponds in position and shape to the flange a to be formed on the upper side of the tile.

The frame 9 is provided with an L-shaped shoulder 13, which is so arranged upon the lower side of the frame that it is adapted to project for a certain distance into the slot l2 if the :frames 8 and 9 are jointly lowered upon the mold 2. The depth to which this shoulder enters into the slot is controlled by a stop 9,which, as well as a iinger-piece 82 of frame 8, serves to open and close the frame.

The consecutive posit-ions of the machine are illustrated in Figs. 3 to 7.

The frames 8 and 9 are thrown back, Figs.

1 and 3, to open the mold, which is filled to.

its edge with clay or other body to be molded, such clay being rammed or beaten down and scraped smooth. The frame 8,with slide l0 open, is now folded upon the mold 2, Fig. 4,-

and the slot l2 is likewise filled with clay. The slide 10 is then drawn forward by handle 102 to project over the slot 12 and cut off smoothly the excess ofthe clay, Fig. 5. The roofing-tile having a flange a of the proper height and the exact rectilinear shape is thus formed within the mold. In order to permit this molded tile to be removed without causing the flange a to be injured or torn 0H by the opening of the frame 8, the frame 9 is broughtinto action. This frame is now folded down, so as to lie, with its shoulder 13, upon the flange a, Fig. 6, and by slowly raising the frame 8 the stop 9' is pressed against the fin-4 ger-piece S2. By this raising of the frame 8 the shoulder 13 will slowly push the flange a out of the slot 12 without injuring the flange, and then both the frames 8 and 9 may be entirely thrown back f-rom the mold Without producing an injurious effect. A pressure upon treadle 6 will now raise the `false bottom 2,with the iinished tile, out of the mold 2, Fig. 7, so that the tile can be removed.
